Denmark
Denmark, a Nordic nation in Northern Europe, is identified internationally by the ISO 3166-1 codes DK (two-letter) and DNK (three-letter), used in global trade, logistics, and data systems. Its telecommunications infrastructure relies on the country calling code +45, which must be dialed for inbound international calls, replacing the local trunk prefix. The country-code top-level domain (ccTLD) is .dk, reserved for Danish businesses, organizations, and residents seeking local web presence and search visibility. Denmark's official currency is the Danish Krone, abbreviated DKK, a key factor in financial transactions, invoicing, and e-commerce. These identifiers are essential for contact, web registration, and commercial operations within the European market.

How to call Denmark
From outside Denmark, dial your international access prefix, then +45, then the national number. Drop the leading trunk zero when the destination numbering plan requires it.
